<P><STRONG>Functional Details</STRONG>
<P>
This module sends variable values from a visual program to a remote
application that uses the DXLink library of function calls
(see <A HREF="progu084.htm#HDRDXLINK">Chapter 17. "DXLink Developer's
Toolkit"</A> in <I>IBM Visualization Data Explorer Programmer&#39;s
Reference</I>).
Values are sent as strings and in the same format as that used by the
Echo tool.
<TABLE CELLPADDING="3">
<TR VALIGN="TOP"><TD><P><B><TT><STRONG>label</STRONG></TT>
</B></TD><TD><P>is similar in function to the label set in the DXLInput
configuration dialog box in that it associates a name
(i.e., a global variable name)
with a value.
This global variable name is used in the
<TT><STRONG>DXLSetValueHandler()</STRONG></TT> routine
of the DXLink library (see <A HREF="progu089.htm#HDRRCVMSG">"Receiving Messages
from the Server"</A>
in <I>IBM Visualization Data Explorer Programmer&#39;s Reference</I>).
<P>
The remote application should install a handler for the various
<TT><STRONG>label</STRONG></TT>ed global variable names in a program
(see DXLSetValueHandler in <A HREF="progu089.htm#HDRRCVMSG">"Receiving Messages
from the Server"</A> in <I>IBM Visualization Data Explorer Programmer&#39;s
Reference</I>).
In general, <TT><STRONG>label</STRONG></TT> values should be unique within a
program.
<P><B>Note: </B>If you are using the Data Explorer user interface,
<TT><STRONG>label</STRONG></TT> does not appear as
an input parameter but is set in the
<TT><STRONG>notation</STRONG></TT> field
of the DXLOutput configuration
dialog box.
</TD></TR><TR VALIGN="TOP"><TD><P><B><TT><STRONG>value</STRONG></TT>
</B></TD><TD><P>is the value that is to be converted to a string and sent to
a remote application.
This value must be a Data Explorer value list or string (e.g., a scalar,
integer list, matrix, etc.).
It cannot be a Field or Group object.
